Glucagon-like peptides.
Proglucagon contains the sequence of two glucagon-like peptides, GLP-1 and GLP-2, secreted from enteroendocrine cells of the small and large intestine. GLP-1 lowers blood glucose in both NIDDM and IDDM patients and may be therapeutically useful for treatment of patients with diabetes. GLP-1 regulates blood glucose via stimulation of glucose-dependent insulin secretion, inhibition of gastric emp...
متن کاملEvidence for transformation of glucagon-like immunoreactivity of gut into pancreatic glucagon in vivo.
The effect of gut glucagon-like immunoreactivity (GLI) devoid of pancreatic glucagon was studied in piglets. All glucagon-like peptides with an accessible C-terminal were removed from the gut extract by specific antibodies reacting with the C-terminal of the glucagon molecule. Endogenous secretion of pancreatic and gut glucagon was blocked by somatostatin infusion, and then the purified gut glu...
متن کاملMinireview: the glucagon-like peptides.
The glucagon-like peptides GLP-1 and GLP-2 are produced in enteroendocrine L cells of the small and large intestine and secreted in a nutrient-dependent manner. GLP-1 regulates nutrient assimilation via inhibition of gastric emptying and food intake. GLP-1 controls blood glucose following nutrient absorption via stimulation of glucose-dependent insulin secretion, insulin biosynthesis, islet pro...
متن کاملGut adaptation and the glucagon-like peptides.
The glucagon-like peptides GLP-1 and GLP-2 are synthesised and then released from enteroendocrine cells in the small and large intestine. GLP-1 promotes efficient nutrient assimilation while GLP-2 regulates energy absorption via effects on nutrient intake, gastric acid secretion and gastric emptying, nutrient absorption, and mucosal permeability. Preliminary human studies indicate that GLP-2 ma...
متن کاملCirculating and tissue forms of the intestinal growth factor, glucagon-like peptide-2.
Glucagon-like peptide-2 (GLP-2) has recently been identified as a stimulator of intestinal epithelial growth, prompting the development of RIA and HPLC methodologies to study this peptide in more detail. A GLP-2-specific antiserum (UTTH-7) was developed that recognizes amino acids 25-30 of human and rat GLP-2-(1-33). UTTH-7 cross-reacts with N- and C-terminally modified forms of GLP-2, progluca...
